Those skilled in the art should understand that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, elements and circuits well known to those skilled in the art are not described in detail in order to highlight the main idea of the present disclosure.

[0047] In order to overcome the problems in the related art, the present disclosure proposes a paint coating injector manufacturing mechanism, which can automatically configure paint coating by rotating a plurality of raw material injectors on a turntable of a paint coating configuration module above a needle cylinder and outputting a preset amount of raw material, improving the accuracy of the amount, and improving the quality of the paint coating. And by the injector manufacturing module, the piston rod is pressed into the needle cylinder to obtain an injector containing paint coating. During the configuration process of the paint coating and the subsequent use process, no pipeline is needed, no pipeline cleaning is needed, and the waste of raw materials or paint coating in the pipeline is reduced.

[0048] Figure 1 A block diagram of a paint coating injector manufacturing mechanism according to an embodiment of the present disclosure is shown. The paint coating configuration module and the injector manufacturing module;

[0049] The paint coating configuration module includes a turntable with a plurality of raw material stations, a needle cylinder on a weight sensor below the turntable, the paint coating configuration module is configured to rotate the raw material injectors arranged in the plurality of raw material stations to above the needle cylinder through the turntable, and output a preset amount of raw material into the needle cylinder, and the weight sensor is configured to measure the amount of raw material in the needle cylinder;

[0050] The injector manufacturing module is used to press the piston rod into the syringe to obtain a paint injector, wherein the piston rod is a piston rod with an axial through hole, and paint is output through the axial through hole of the piston rod by axial movement of the piston rod in the syringe.

[0051] In a possible implementation, the set multiple raw material injectors can be placed into multiple raw material stations on a turntable of the paint configuration module by a robot, and the placement positions of each raw material injector can be recorded, so that the type and amount of raw material at each raw material station can be determined during the configuration process. In an example, the number of raw material stations on the turntable is 9, and the disclosure does not limit the specific number of raw material stations on the turntable.

[0052] In a possible implementation, during the configuration process, the paint configuration module can rotate each raw material station above the syringe according to the set configuration steps, so as to align the raw material injector placed at each raw material station with the syringe and make each raw material injector output a preset amount of raw material. In an example, the paint configuration module can rotate a first raw material station above the syringe, and make the raw material injector placed at the raw material station (for example, the type of raw material in the raw material injector is type A) output X grams of raw material, then rotate a second raw material station above the syringe, and make the raw material injector placed at the raw material station (for example, the type of raw material in the raw material injector is type B) output Y grams of raw material, and rotate a third raw material station above the syringe, and make the raw material injector placed at the raw material station (for example, the type of raw material in the raw material injector is type C) output Z grams of raw material, so that the syringe can contain X grams of type A raw material, Y grams of type B raw material, Z grams of type C raw material, and the like. The weighing of the amount of raw material injected into the syringe can be completed by a weight sensor.

[0053] In a possible implementation, the multiple types of raw materials contained in the syringe can be stirred and subjected to viscosity testing, so as to uniformly stir the raw materials and make the viscosity appropriate for subsequent use.

[0054] In a possible implementation, the syringe containing the stirred paint can be delivered to the injector manufacturing module, so as to install a piston rod for the syringe to obtain a paint injector. When the paint in the paint injector is used, the piston rod can be moved axially along the syringe, that is, the piston rod is pressed or pushed, and the paint in the syringe can be output through the axial through hole of the piston rod.

[0055] Figure 2 A schematic view of a paint injector manufacturing mechanism according to an embodiment of the disclosure is shown as follows, Figure 2As shown, the paint coating module comprises a rotating disc 1 with a plurality of raw material stations, each raw material station is provided with a raw material injector 3, a needle cylinder 6 is provided at a preset position below the rotating disc, the position of the needle cylinder 6 is fixed, when the paint is coated, the rotating disc 1 can rotate each raw material injector 3 to above the needle cylinder 6 and output a preset amount of raw material.

[0056] In a possible implementation, the paint coating module further comprises a first linear module 2 and an injector pressing plate 4, the injector pressing plate 4 is arranged on the first linear module 2; the paint coating module is further used for: when the raw material injector 3 is rotated to above the needle cylinder 6 by the rotating disc 1, moving the injector pressing plate 4 downward by a preset distance through the first linear module 2 to press the raw material injector 3 downward, so that the raw material injector 3 outputs a preset amount of raw material.

[0057] In an example, the injector pressing plate 4 can be driven by a motor, a cylinder or the like, the driving mechanism of the injector pressing plate 4 is not limited in the present disclosure, the injector pressing plate 4 can be arranged directly above the preset position of the needle cylinder 6, so that the raw material injector 4 above the needle cylinder can be pressed downward by a preset distance along the first linear module 2, so that the raw material in the raw material injector 4 is outputted by a preset amount and accurately falls into the needle cylinder 6.

[0058] In a possible implementation, the rotating disc 1 can be driven to rotate by a motor or the like, the driving mechanism of the rotating disc 1 is not limited in the present disclosure. The first linear module 2 and the injector pressing plate 4 do not rotate with the rotating disc, so that the injector pressing plate 4 is always above the needle cylinder 6.

[0059] In a possible implementation, in order to further improve the accuracy of the amount of raw material, the paint coating module further comprises a weight sensor 5; the weight sensor 5 is used for weighing the raw material inputted into the needle cylinder 6. That is, when the weight of the raw material inputted into the needle cylinder 6 reaches a preset amount, the injector pressing plate 4 stops pressing downward and the raw material injector 3 stops outputting raw material.

[0060] In a possible implementation, during the process of pressing the raw material injector downward by the injector pressing plate 4, the pressing speed of the injector pressing plate 4 can be controlled, so as to further improve the accuracy of the amount of raw material inputted into the needle cylinder 6, in an example, the pressing speed of the injector pressing plate can be determined according to formula (1):

[0061] (1)

[0062] wherein, and is the weight of the raw material inputted into the needle cylinder 6 per unit time, and > , is the preset amount of material, is the variable speed threshold, is the radius of the material injector, is the density of the material, m is the weight of the material measured by the weight sensor.

[0063] In an example, when the weight of the material measured by the weight sensor reaches before the preset amount of material, i.e. the difference between the weight of the material measured by the weight sensor and the preset amount of material is , the pressing of the injector pressing plate can be performed at a faster speed, so as to increase the pressing speed and improve the configuration efficiency. When the weight of the material measured by the weight sensor reaches after the preset amount of material, the pressing of the injector pressing plate is performed at a slower speed, so as to more accurately control the output amount of the material.

[0064] In an example, when the relationship between M T , the relationship between m1 and m2 is as follows, the present application can more accurately control the amount of material injected into the syringe 6.

[0065] M T =a*M, where a≤0.3, when M≤100, preferably a=0.2, when 100

[0066] m1=b*m2, where 5≤k2≤20, preferably b=10.

[0067] In an example, M is set to 500g, M T may be set to 5g, m1 may be set to 5g / s, m2 may be set to 0.5g / s, R is 25mm, and ρ=1.5g / cm 3 When the difference between the weight of the material measured by the weight sensor and the preset amount of material is greater than 5g, the pressing speed of the injector pressing plate is 1.7 (mm / s), and when the difference between the weight of the material measured by the weight sensor and the preset amount of material is less than or equal to 5g, the pressing speed of the injector pressing plate is 0.17 (mm / s).

[0068] In an example, M is set to 50g, M T may be set to 5g, m1 may be set to 5g / s, m2 may be set to 0.25g / s, R is 25mm, and ρ=1.5g / cm 3 When the difference between the weight of the material measured by the weight sensor and the preset amount of material is greater than 5g, the pressing speed of the injector pressing plate is 1.7 (mm / s), and when the difference between the weight of the material measured by the weight sensor and the preset amount of material is less than or equal to 5g, the pressing speed of the injector pressing plate is 0.08 (mm / s).

[0069] In a possible implementation, the weight sensor can be replaced by an electronic scale.

[0070] In a possible implementation, the paint coating configuration module further comprises a leakage-proof container 7; the leakage-proof container 7 is arranged below each raw material injector 3 and is used to contain the raw material dripped from the raw material injector. In an example, the raw material injector 3 may, when at rest or before or after injection, drip some raw material. In order to avoid the pollution caused by the dripping of the raw material, the leakage-proof container can be arranged below the raw material injector 3, so that the dripping raw material enters the leakage-proof container 7 and avoids polluting other positions.

[0071] In a possible implementation, the paint coating configuration module further comprises a compression spring 8 and a first cylinder 9; the compression spring 8 is arranged behind the leakage-proof container; and the paint coating configuration module is further configured to: when the raw material injector 3 is rotated above the needle cylinder 6 by the rotating disc 1, drive the compression spring 8 by the first cylinder 9, so that the compression spring 8 pushes away the leakage-proof container 7 and enables the raw material in the raw material injector 3 to enter the needle cylinder 6.

[0072] In a possible implementation, the leakage-proof container 7 is arranged directly below each raw material injector 3 to prevent the dripping of the raw material. When the raw material injector 3 is used, the leakage-proof container 7 can be removed to avoid the leakage-proof container 7 hindering the raw material in the raw material injector 3 from falling into the needle cylinder 6. In an example, the leakage-proof container 7 can be pushed away from the falling path of the raw material in the raw material injector 3 by driving the compression spring 8 by the first cylinder 9, so that the raw material in the raw material injector 3 falls smoothly into the needle cylinder 6.

[0073] In a possible implementation, the leakage-proof container 7 comprises a container and a through hole beside the container, the container is arranged below the raw material injector 3 when the raw material injector 3 is not rotated above the needle cylinder; and the pushing away of the leakage-proof container 7 by the compression spring 8 comprises: pushing the leakage-proof container 7 by the compression spring 8, so that the through hole beside the container is arranged below the raw material injector 3.

[0074] In a possible implementation, the front end of the leakage-proof container 7 is the container and the rear end is the through hole. When the raw material injector 3 is used, the leakage-proof container 7 can be pushed forward by the compression spring 8 driven by the first cylinder 9, so that the container originally arranged below the raw material injector 3 moves forward and the through hole is arranged below the raw material injector 3. Thus, when the raw material injector 3 outputs the raw material, the raw material can fall into the needle cylinder through the through hole.

[0075] In a possible implementation, after the raw material injector 3 is used up, the injector pressing plate 4 can remove the downward pressure so that the raw material injector 3 no longer outputs the raw material, and the first air cylinder 9 can remove the pushing force so that the leakage-proof container 7 returns to the original position, i.e., the container is located below the raw material injector 3 again to avoid the raw material from dripping. Further, the rotating disc 1 can be rotated so that the next raw material injector 3 moves above the needle cylinder 6, and the leakage-proof container 7 is driven by the first air cylinder 9 to push the compression spring 8 to move the through hole below the raw material injector 3, and the raw material injector 3 is pressed by the injector pressing plate 4 to output a preset amount of raw material. After the output is completed, the above process can be repeated again, i.e., the injector pressing plate 4 removes the downward pressure, the first air cylinder 9 removes the pushing force, and the above process can be repeatedly executed until the required multiple raw materials are injected into the needle cylinder 6 according to the preset amount.

[0076] In a possible implementation, after the required raw materials are injected into the needle cylinder 6 according to the preset amount, the needle cylinder 6 can be transported to the injector manufacturing module, and a piston rod is installed in the needle cylinder. The piston rod can be placed on the injector manufacturing module, and when the needle cylinder 6 is transported below the piston rod in the injector manufacturing module, the injector manufacturing module can press the piston rod into the needle cylinder 6 to obtain a paint injector.

[0077] In a possible implementation, the injector manufacturing module comprises a conveying line 10, and the conveying line 10 is used to transport the needle cylinder 6 containing multiple raw materials below the piston rod 12. In an example, the needle cylinder 6 can be placed on the conveying line 10 by a robot, and can be transported to the injector manufacturing module by the conveying line 10. Further, during the transportation of the conveying line 10, the multiple raw materials in the needle cylinder 6 can be stirred and tested for viscosity by other mechanisms (for example, stirring mechanisms and viscosity testing mechanisms) so that the multiple raw materials in the needle cylinder 6 are uniformly mixed and have appropriate viscosity, and thus the paint can be obtained.

[0078] In a possible implementation, the injector manufacturing module further comprises a clamping air cylinder 11 arranged on the opposite side of the second linear module 13 and used to position and clamp the needle cylinder 6. In an example, the needle cylinder 6 can be clamped before being transported below the piston rod 12, and before the piston rod 12 enters the needle cylinder 6 by the second linear module 13, to prevent shaking during the pressing of the piston rod 12. Further, the clamping air cylinder 11 is arranged directly below the piston rod 12, and can position the needle cylinder 6 directly below the piston rod 12 to facilitate the accurate entry of the piston rod 12 into the needle cylinder 6. Further, after the installation of the piston rod 12 and the needle cylinder 6 is completed, the clamping air cylinder 11 can be opened to transfer the paint injector for use in subsequent processes.

[0079] Figure 3A schematic view of a syringe manufacturing module according to an embodiment of the present disclosure is shown.

[0080] In a possible implementation, the syringe manufacturing module comprises a second linear module 13, a second air cylinder 14, a positioning plate 19 and a pressing plate 16; the second linear module 13 is a vertical linear module for carrying the piston rod 12 to move in the vertical direction; the positioning plate 19 is arranged on the second linear module 13 for placing the piston rod 12; the second air cylinder 14 is used to drive the pressing plate 16 so that the piston rod 12 is fastened on the positioning plate 19.

[0081] The syringe manufacturing module is further used to move the piston rod 12 downward along the second linear module 13 so that the piston rod 12 enters the needle cylinder 6. In an example, the positioning plate 19 can move along the second linear module 13 by the air cylinder 17, i.e., carrying the piston rod 12 to move along the second linear module 13, so that the piston rod 12 moves downward into the needle cylinder 6.

[0082] In a possible implementation, the syringe manufacturing module comprises an optical fiber sensor 18; the optical fiber sensor 18 is arranged on the pressing plate 16 for detecting whether there is paint coating on the top end of the axial through hole of the piston rod 12.

[0083] The syringe manufacturing module is further used to stop the downward movement of the positioning plate 19 when the optical fiber sensor 18 detects that there is paint coating on the top end of the axial through hole of the piston rod 12, so as to obtain the paint injection syringe.

[0084] In a possible implementation, after the robot places the piston rod 12 on the positioning plate 19, the second air cylinder 14 can drive the pressing plate 16 to press the piston rod 12, and drive the positioning plate 19 to move downward by the air cylinder 17, so that the piston rod 12 moves downward into the needle cylinder 6. After the piston rod 12 reaches the liquid level in the needle cylinder 6, the paint coating in the needle cylinder 6 will rise through the axial through hole of the piston rod 12, i.e., be discharged through the axial through hole. In other words, when the paint coating is discharged through the axial through hole, the piston rod 12 has reached the liquid level of the paint coating, at this time, the air in the needle cylinder 6 has been exhausted, and the piston rod 12 can be stopped from descending. Whether the paint coating is discharged through the axial through hole can be detected by the optical fiber sensor 18. For example, when the paint coating reaches the top end of the axial through hole, the paint coating will block the light of the optical fiber sensor 18, so that the light transmittance of the light decreases. When the optical fiber sensor 18 detects that the light transmittance decreases, it is determined that the paint coating has reached the top end of the axial through hole, i.e., the piston rod has reached the liquid level of the paint coating, at this time, the piston rod 12 can be stopped from descending, and the paint injection syringe is obtained.

[0085] Further, to improve the production efficiency of the paint injector and reduce the probability of the paint overflowing from the top end of the axial through hole, the speed of the downward movement of the piston rod can be controlled. For example, before the piston rod enters the needle cylinder, the downward movement of the piston rod can be fast, i.e., the downward movement of the positioning plate 19 driven by the air cylinder 17 can be fast, so as to improve the production efficiency. After the piston rod enters the needle cylinder, the downward movement of the piston rod can be slow, i.e., the downward movement of the positioning plate 19 driven by the air cylinder 17 can be slow, so as to reduce the probability of the paint overflowing from the top end of the axial through hole. In an example, the height of the needle cylinder can be set such that the downward movement of the piston rod can be fast before the positioning plate 19 driven by the air cylinder 17 moves to the height of the needle cylinder, and the downward movement of the piston rod can be slow after the positioning plate 19 driven by the air cylinder 17 moves to the height of the needle cylinder, e.g., the downward movement of the piston rod can be slow to 1 / 10 of the previous speed. The specific values of the downward movement of the piston rod before and after the positioning plate 19 driven by the air cylinder 17 moves to the height of the needle cylinder are not limited in the present disclosure.

[0086] In this way, the air in the needle cylinder can be discharged, the bubbles in the paint can be reduced, and the use amount of the paint in the subsequent use process can be controlled.

[0087] In a possible implementation, the injector manufacturing module can include a mounting seat 15, which can be used to mount the second linear module 13, and the mounting seat 15 can be opposite to the clamping air cylinder 11. The injector manufacturing module can include a code printer 20, which can print codes on the paint injector, so as to facilitate the identification of the paint injector in the subsequent use process.

[0088] In a possible implementation, the above process of manufacturing the paint injector can include: conveying the needle cylinder 6 to below the piston rod 12 through the conveying line 10, and stirring the multiple raw materials in the needle cylinder 6 uniformly and performing viscosity testing during the conveying process. After the needle cylinder 6 is conveyed to below the piston rod 12, the needle cylinder 6 can be clamped by the clamping air cylinder 11, then the piston rod 12 can be moved downward along the second linear module 13 and enter the needle cylinder 6, further, the second air cylinder 14 can press the piston rod 12 tightly, so that the piston rod 12 is combined with the needle cylinder 6 more firmly, and the paint injector is obtained. Further, the clamping air cylinder 11 can be opened, and the paint injector can be transferred for subsequent use.

[0089] The paint injection device manufacturing mechanism according to the embodiments of the present disclosure can automatically configure paint by rotating the plurality of raw material injectors on the carousel of the paint configuration module to above the syringe and outputting a preset amount of raw material, and improving the accuracy of the amount by the weight sensor, thereby improving the quality of the paint. A leakage-proof container is arranged below the raw material injector to avoid raw material dripping and contaminating other locations. Further, the piston rod can be pressed into the syringe by the injection device manufacturing module, and the piston rod can be tightly fixed by the second cylinder, so that the piston rod does not shake during installation of the piston rod. The syringe can be clamped by the clamping cylinder to avoid shaking of the syringe during pressing of the piston rod. The optical fiber sensor can be used to determine whether the piston rod reaches the liquid level position in the syringe, so that the air in the syringe can be discharged, the bubbles in the paint can be reduced, and the amount of paint used in the subsequent use process can be controlled. During the configuration process of the paint and the subsequent use process, no pipeline is needed, the pipeline does not need to be cleaned, the waste of raw material or paint in the pipeline is reduced, and the paint configuration process is suitable for various raw materials.

[0090] It can be understood that the above-mentioned embodiments mentioned in the present disclosure can be combined with each other to form a combined embodiment without deviating from the principle logic.
